Hi,

I'm facing an issue with line-breaks tags when they are written like <br/> instead of <br>.

Considering this simple example:

>>> import markdownify
>>> markdownify.markdownify("<p>11111<br>22222<br>33333<br/>44444<br><55555</p>", heading_style=markdownify.ATX)

Expected:

'11111  \n22222  \n33333  \n44444  \n55555 \n\n'

Actual:

'11111  \n22222  \n33333  \n\n\n'

My workaround is to .replace('<br/>','<br>') but it's a little pity...

Could you fix this in a future release?

Regards,
